Zz and jk strains can breed as little as 3 inches becoming sexually active at around 4 months old . At least the females anyway . Males can become sexually mature around 5 months and 3 -4 inches . This will vary with each individual fish .
agreed but have heard from some experianced ones that breeding so small can lead to instable fry..shorter life span
ever heard off this?
some off my best batch from little ones
Yes ive heard this for many many years . As far as proof.... ummmm, i dont know if there is any . I myself dont particulary believe this since i have bred fish young alot of times. I have also bred fish at an older age and havent seen any difference in the quality or life span of the offspring . I know a few people here locally that have done this also with bigger fish . You see i feel that if a fish is able to breed then there is nothing wrong for it to breed . Some big cichlids come into maturity at 4 months of age and yet others like Oscars for example take a year to 2 years . You see , its "mother natures" way of telling the fish that its time to breed. Sure alot of fish have seasons that they breed in and are forced to wait a whole year before they breed . But the same fish in another climate that offers longer warmer springs and summers will alow a fish to be born at the beggining of the season and sexually mature and spawn before the end of the long season .
I also dont believe that male fish are stunted through breeding. I started to believe this at one time but i dont anymore. I have a friend who had some 24 inch male breeder oscars that he bought then when they were about 10 inches . They bred for years . They ended up growing to a phenomenal length . The females stayed alot smaller because they were putting out alot of protein through egg production . But the males kept growing large.
So maybe the suggestion that babies will be a smaller fish than what they could be if the parents are bred young. But i personally dont believe this .
My fry had a daddy that wasnt a year old . They also had a mother that was significantly younger than a year old. Their fry are now 7 months old. I have two males upstairs that are on growth track and healthy as can be . They are extreemly mean . I also have another fry that is going on 9 inches and is over his growth track . Hes even meaner . Yes i had some that grew significantly under what they should have grown but this was only because they were in the same tank as the big ones , thats all . So no i dont believe that breeding young fish has anything to do with there life span or health . I personally believe this is a mith . At least in fish . Until someone has done scrupulous testing and testing and then more testing , i dont think that there is any validity in the conclusion that young fish will throw off less quality fry . But i could be wrong . These are just my two cents . There is no proof in my beliefs either . Just want to make that clear.
Whatever the case , i dont think theres going to be that much difference whatever age you decide to breed your fish . Its no big deal to me . Just enjoy the fish while its alive .
if they r sexually mature and are able to breed
there shouldnt be any reason for them not being capable to produce long living fry.
thats a good point you make about using protein for egg production.
i have noticed that too, when female are spawning, they grow much slower.
Partly also because there diet is lower and they are buring up much more energy.
But lets not forget... if eggs require high protein and the female has lower capability because of size, there could be room for malnurishment.
Larger females produce larger, more healthy eggs than smaller ones.
Larger males have higher sperm count.
after spawn.. even size of free swimmers is larger " some times "
could this show some relation to the belief of poor quality ??
i dont believe it.
